Commit Message

William Breathitt Gray Nov. 1, 2024, 7:15 a.m. UTC 
pcim_iomap_regions() and pcim_iomap_table() have been deprecated in
commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()"). Replace these functions with
pcim_iomap_region().

In order to match the rest of the code in idio_16_probe(), utilize
dev_err_probe() to handle error for pcim_enable_device().
